4*tesp ; 7 ¶ *ia,54-74,16-3; ,777; Dr. Irvin noted he was suggesting a,series of motions to be sent to the Board of Commissioners. Smithlindicated that the staff concern regarding the approach-departure zone is the control of natural obstacles in the zone, adding that the Zoning Ordinance addresses the control of man-made obstacles which may intrude the approach-departure zone. Shank/in felt the control of obstacles was the developer's concern and could be addressed by shifting the touchdown point on the runway. Pearson inquired how much distance : was required to land an airplane. Shanklin responded that a plane could be landed in less that 2,000 feet. Pilkeyl asked if a small jet could land in that distance. Collins indicated that the conditions of the Special Use Permit precluded jets landing at the airport. Shanklin :continued that heavier engines can displace a threshholc halfway down the runway. Smith cited the March 17, 1983 letter from the FAA indicating a concern for the control of naturally occurring obstacles as the purpose of the approach- departure area. Shanklin indicated that this is a problem for the airport operatOr and noted that a naturally occurring obstacle becomes a "controllling obstacle" which determines the floor of the approach. For every foot of tree intruding into the approach-departure surface,the minimum for the approach floor goes up 100 feet for an instrument approach. Gordon asked a procedural question about whether the Board had to go through the findings of fact for a recommendation on the modifications. Irvin responded yes, Gordon indicated she understood that for the specific requiretbents, but wondered about the general standards. Irvin responded that ifIthese were pertinent to the decision then they would have to be discussed. Gordon felt this was a critical, point regarding specific standard (c) for a general aviation airport. She specifically asked if Orange County can be more strict than the FAA standards, Irvin responded that this issue was addressed in the last paragraph of page four of the paper regarding Richard Ducker's comments. GordonEeked how they should deal with a condition approved which may or may not be a "mistake", Irvin responded that a "mistake" would suggest a condition was too restrictive and action would have to be taken to modify the condition., He noted that the ordinance calls for a 5000 foot approachldeparture zone. Lee Mehler, Peloquin Associates, disagreed saying that the ordinance does not require a 5000 foot zone. He also added that it was not cut and dry whether a) and (c) were separate items, He stated that the State regulations do not require a 5000 foot zone. Irvin responded that this was a County requiremtt. Mehler again stated the ordinance does nni- cn,a;,;;- cnnn r Dr
